What FLOWBIO does
FLOWBIO is a London-based sports technology company founded in 2020 that develops a non-invasive biowearable sweat sensor and accompanying intelligence platform for endurance athletes. Its core product, the FLOWBIO Sensor, is a reusable upper-arm wearable that uses microfluidic sweat capture and ion-selective electrode technology to measure real-time sweat rate and sodium concentration during exercise, with skin temperature and ambient sensors integrated and 100+ hour battery life via USB-C. Sensor data feeds the FLOWBIO App and the proprietary AHi (Advanced Hydration Intelligence) platform, which combines physiological inputs with effort and environmental data to generate personalized hydration recommendations through the Hydration Planner feature.
The company monetizes primarily through one-time hardware sales of the sensor via DTC e-commerce (flowbio.com), specialty retail stockists (The Feed, Sigma Sports, Healf, Aid Station), and a global AHi Experience Partners network of coaches, performance centers, and bike fitters offering sweat profiling services. Supplementary revenue streams include B2B sweat testing services, the London-based Book A Sweat Test experience, in-app supplements and consumption tracking, and event-based deployment at Ultra X trail races in partnership with Science in Sport. Real-time sensor data streams natively to Wahoo ELEMNT ACE, BOLT 3, and ROAM bike computers, with Garmin, Coros, Zwift, and Suunto integrations in development or beta. FLOWBIO is privately held, has raised £879,050 via Crowdcube (May 2022) alongside earlier rounds backed by SOSV HAX and Entrepreneurs First, and hand-builds its sensors at its Bermondsey lab in London.

FLOWBIO product offering
Product offeringCore offering
FLOWBIO designs, hand-builds, and sells a reusable arm-based sweat sensor that measures real-time sweat rate and sodium concentration during exercise. The sensor pairs with the FLOWBIO mobile app and the proprietary Advanced Hydration Intelligence (AHi) platform, which converts physiological and environmental inputs into personalized session and race hydration plans. Revenue is anchored on a one-time hardware purchase, supplemented by professional sweat testing services delivered directly and through a global partner network.
Product overview
FLOWBIO offers a unified hydration intelligence system centered on the FLOWBIO Sensor—a reusable arm-based sweat sensor that measures fluid and sodium loss during exercise—and the FLOWBIO App with AHi (Advanced Hydration Intelligence) platform. AHi processes real-time sweat data combined with environmental and effort data to deliver personalized hydration recommendations through the Hydration Planner. The ecosystem includes the Supplements & Consumption tracking feature, the AHi Experience Partners network for professional testing services, and the Book A Sweat Test service for hands-on profiling. Prior products include the Flowpatch (2021, disposable-patch based) and S1 (2023, first fully reusable sensor).
Differentiator

Brands
- AHi (Advanced Hydration Intelligence): The brains behind the FLOWBIO System - the sensor and app working together. Combines sweat data (fluid and sodium loss) with temperature and intensity data to deliver personalized hydration insights.
Products and services
- FLOWBIO Sensor A reusable, non-invasive arm-based sweat sensor that measures real-time sweat rate and sodium concentration during exercise for endurance athletes (runners, cyclists, triathletes, ultrarunners). Streams live fluid and sodium data to the FLOWBIO App and to compatible third-party bike computers and watches.
- FLOWBIO App Companion iOS and Android application that syncs with the FLOWBIO Sensor to display real-time sweat data, host the AHi Hydration Planner, and deliver personalised hydration, recovery, and preparation recommendations for endurance athletes.
- Book A Sweat Test Professional sweat testing service in which athletes book sessions at the FLOWBIO Lab in London or with AHi Experience Partners, and can take the FLOWBIO Sensor home for a complimentary 3-day trial integrated into their training before committing to purchase.
